a, X = 1. b, X = 17. ĐOÁN LÁO THÔI HÌ.
12:3=4x2=8-7=1
a/x=1
16:2=8x1=25-8=17
b/x=17 tick nha
tìm x , biết :
a) \(\frac{7+x}{12}=\frac{2}{3}\)
b)\(\frac{25-x}{8}=\frac{1}{2}\)
Tìm x \(1-\left(x\%+x:50+\frac{\frac{3}{2}-\frac{3}{7}-\frac{3}{13}}{\frac{25}{2}-\frac{25}{7}-\frac{25}{13}}\times x\right)=0\)
ĐỀ: TÌM X
\(a,\frac{7}{5}:x+\frac{3}{2}=\frac{16}{3}\)
\(b,x:\frac{1}{5}+\frac{1}{7}=\frac{3}{5}.\frac{18}{21}\)
\(c,x-1\frac{1}{3}:2=\frac{5}{7}\)
\(d,x+2\frac{3}{5}.\frac{1}{6}=\frac{35}{36}\)
\(e,\left(x+\frac{3}{2}\right):2=\frac{7}{10}+\frac{1}{5}\)

Tìm x là số tự nhiên biết :
a) \(\frac{x}{17}=\frac{60}{204}\) b) \(\frac{6+x}{33}=\frac{7}{11}\) c) \(\frac{12+x}{43-x}=\frac{2}{3}\)
d)\(\frac{x}{5}< \frac{3}{7}\) e) \(1< \frac{11}{x}< 2\) g) \(\frac{15}{26}+\frac{x}{16}=\frac{46}{52}\)
HELP ME !
Tìm x biết:
a, \(\frac{x:3-16}{2}\)+21=38
b, \(\frac{1}{4}+\frac{1}{3}:\frac{1}{x}=\frac{11}{12}\)
c, 4+\(\frac{1}{3}+\frac{1}{6}+\frac{1}{10}+\frac{1}{15}+...+\)\(\frac{2}{xXx\left(x+1\right)}\)
Tìm X biết
a) \(x\cdot\frac{2}{7}\cdot\frac{3}{4}=\frac{5}{21}\)
b) \(x\cdot\frac{1}{2}=\frac{1}{3}\)
c) \(x:\frac{4}{5}=\frac{25}{8}:\frac{5}{4}\)
a)\(\frac{3}{5}-\frac{1}{3}-\frac{1}{6}\)
b)\(\frac{4}{7}x\frac{5}{8}x\frac{7}{12}\)
c)\(\frac{25}{28}:\frac{15}{14}x\frac{6}{7}\)
Tìm x;
(\(\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}\)) : x = (\(\frac{1}{2}+\frac{1}{6}+\frac{1}{12}+\frac{1}{20}+.......+\frac{1}{132}\))
tìm x biết: \(\frac{\left(\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}\right)}{x}=\frac{1}{2}+\frac{1}{6}+\frac{1}{12}+\frac{1}{20}+...+\frac{1}{132}\)
